Engineered Newcastle disease virus expressing the F and G proteins of AMPV-C confers protection against challenges in turkeys

Live attenuated vaccines appear to be the most effective in countries where the disease is prevalent. However, reversion to virulence has been demonstrated in several studies. Therefore, the development of a stable and safe next generation vaccine against the AMPV disease is needed. In the...
